Well, I reviewed the diagram you provided and sure enough I had the hose from the rear vane pump in the incorrect location. I re routed the hoses as per the diagram and the machine is back to operating as it should. I guess in my rush of trying to put it back together before the holidays I must have overlooked this. I would like to thank everyone who assisted with this and especially Oldnslo, thank you for going out of your way to help out. Hope everyone has a great new year !
